Reward Minerals has appealed to the Commonwealth Attorney General to have last month's decision by the Native Title Tribunal over the Lake Disappointment project overruled.
The National Native Title Tribunal refused Reward access to its Lake Disappointment potash project without the consent of the Martu Native Title Party.
Last year, Reward struck a landmark deal with the Martu people who would own more than 10 per cent of the company should they permit Reward access to the project.
However both parties were not able to reach agreement on commercial terms and the deal was called off in August.
Today, Reward, through its subsidiary Holocene, said it has requested the Attorney General make a declaration that the Tribunal's decision is "overruled, with or without conditions".
"Holocene has made the request on the grounds that a potash production facility at Lake Disappointment is in the national interest, and in the interests of the State of Western Australia," it said.
"Holocene has also submitted to the Attorney General that the effect of the grant of the mining lease on the Martu Peoples' native title will not be substantial, and that the Martu People will benefit from the mining lease being granted.
Reward added that any declaration by the Attorney General must be made within two months, during which the company will continue talks with the Party regarding a mining agreement for Lake Disappointment.
